FIFO vs LIFO:- Caveat Emptor

This is old news, but a reminder may help someone out there. I have a 200GB bundle that is coming to an end. Last month I purchased a 1 month data bundle in error instead of a replacement. Contacted Cell C help line immediatly, got called back and told that as I had already used some of the "new" bundle they couldn't reverse the purchase. Used it in an updating orgy instead.

Yesterday, I bought a replacement 200GB bundle, a few MB of the old one being left over, now, surprise, it's using the OLD one first! Looks like accounting practices vary as it may suit the service provider.
